X-Git-Tag: accepted/tizen/common/20141203.182822~1935^2~255
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=45c64940c8bb64a042464ecec89d95eb4cce9b07;p=platform%2Fkernel%2Flinux-arm64.git

kernel/sys.c:do_sysinfo(): use get_monotonic_boottime()

Change do_sysinfo() to use get_monotonic_boottime() instead of
do_posix_clock_monotonic_gettime() + monotonic_to_bootbased().
